BATCHPUMP: AN ALTERNATIVE TO CONVENTIONAL BLOW TANKS

The pursuit of better energy efficiency solutions is a constant subject. Here we present a number of results obtained during the development of an industrial equipment; a bulk solids feeder called Batchpump. With the proposal of being an alternative to the conventional blow tanks, having as main differentials: energy efficiency; simpler installation; lower dimensions; and lower cost of production. In this work there is presented the results obtained for both the Batchpump and a conventional blow tank applied to a  pneumatic conveying system, with limestone powder, on a pipeline with 133m of total length, with an inlet pressure of 4 bar, the Batchpump obtained results of conveying rate being 25% lower and the air consumption being 30% lower validating the initial hypothesis: to consume less energy with comparable transport rate. We present in the results the data in steady state transport cycle in dense phase regime.
